Applicability of risk scores for postoperative nausea and vomiting in a Taiwanese population undergoing general anaesthesia

摘要: Five popular scoring systems for postoperative nausea and vomiting (PONV) were validated compared with two new predictive models in a Taiwanese population. Nine hundred ninety-two patients receiving general anaesthesia tertiary hospital investigated prospective observational cohort study. Patient demographic data the incidence of or first 24 hours after surgery recorded. The overall PONV was 42%. area under curve (AUC) five published risk 0.62 to 0.67. Logistic regression analysis this study showed that female sex history PONV/car sickness only statistically significant independent factors (likelihood ratio test P <0.001).The AUCs our two-predictor gender-only 0.668 0.643, respectively (Nagelkerke R² = 0.122 0.109). Goodness-of-fit model predicted outcome agreement observed (P=0.973). Both Apfel score had similar AUC significantly different from other models. population simplified Koivuranta Palazzo Evans scores (AUC=0.659 0.632; P=0.137 0.513 respectively). All moderate discrimination power but much simpler. Using gender as predictor 75% sensitivity 54% specificity.
